[jira] Commented: (MAHOUT-145) PartialData mapreduce Random Forests
[ https://issues.apache.org/jira/browse/MAHOUT-145?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12751842#action_12751842 ]
Deneche A. Hakim commented on MAHOUT-145:
-----------------------------------------
bq. * TODO: test the code on a Hadoop 0.20.0 cluster (EC2)
Looks like I'll have to wait till Hadoop 0.20.1 to be able to test on EC2...after creating my own API (with a lot of pain, being a noob), I stumbled upon the following bug [HADOOP-5921|http://issues.apache.org/jira/browse/HADOOP-5921]

> This implementation is based on a suggestion by Ted:
> "modify the original algorithm to build multiple trees for different portions of the data. That loses some of the solidity of the original method, but could actually do better if the splits exposed non-stationary behavior."

I'll try...may take some time but I 'll surely learn a lot (will also need a refill on my pain killers)

That fix has been created. Can you just use trunk?
What about using the Yahoo 0.20 distribution? (
http://developer.yahoo.com/hadoop/distribution/ )
